CrackMe #1 – Source code of my first crackme, crackme was published in 2004, so don’t expect too much (expecting too less is also not a good idea).

CrackMe #2.1 (corrected version) – Source code of my second crackme, it is really old :), but still you can learn something from this source (I hope). It was unsolved few months, but then I received two solutions at the same time (almost the same time :> ), both keygens can be downloaded from ‘crackmes’ section on my homepage (http://rewolf.pl).

CrackMe #3 PaintMe – Source code of one of my simplest and strangest crackmes, I’ve attached compiled crackme, because it was modified after compilation.

CrackMe #4 – Source code of my 4th crackme, a lot of code (partially encrypted), algorithm is also pretty interesting I think. Keygen can be found in ‘crackmes’ section on my homepage (http://rewolf.pl).
